Harpoon Magazine was a free, monthly humor newspaper, distributed at SF Bay Area newsstands from August 1990 through September 1992. It seems that Dylan Williams contributed a number of illustrations to the later issues. Below, I've posted a piece from the June 1992 issue, illustrating an article by Todd Nemet.
Harpoon Magazine ran a lot of comics… this issue features strips by Tom Tomorrow, Bill Griffith, Keith Knight and Jaime Crespo, who also drew a great cover for this issue, which I posted below as well. Somebody has recently scanned and posted most issues of Harpoon Magazine online, and you can currently flip through them here. Not the best quality scans, unfortunately…
